Innovation Program TKI Wind op Zee

The TKI Wind op Zee program is in line with the mission-driven innovation policy that focuses on the societal challenge 'Energy transition and sustainability'. Of the 13 Multi-annual Mission-driven Innovation Programs (MMIPs), MMIP 1 focuses on renewable electricity at sea. TKI Wind op Zee executes this program and is therefore focused on enabling the necessary transition to an affordable, reliable, and sustainable energy supply.

MMIP 1 Offshore Renewable Energy

This MMIP focuses on enabling the required scale-up for offshore renewable energy, especially offshore wind energy, and also other forms of offshore energy in the longer term.

For offshore wind energy, it is obvious that the required scale-up is not fully possible with the current technology and methods. Bottlenecks such as costs, construction rate, spatial planning, safety (e.g. shipping), ecology and integration of very large amounts of electric power in the energy system present themselves.

The innovation task of this MMIP lies in resolving those bottlenecks through three sub-programs and associated innovation themes:

1. Cost Reduction and Optimisation

Five sub-themes have been defined within the theme Cost reduction:

Program Line Cost Reduction and Optimisation

1.1 Zero breakdown & Robotization

This theme focusses on research and development of systems and methods to increase the operational reliability of a wind farm by limiting production failures due to malfunctions, repairs and maintenance. This can be achieved through innovative construction methods, the development of intelligent sensor and monitoring systems for below and above the waterline, applications of self-healing materials and components, and robotization of inspection and maintenance activities.

1.2  Optimal Wind Farm Design

Research and development that aims to increase the production of wind farms. For example: optimization of turbines, better design of the wind farm, location aspects and clusters of wind farms. This also takes into account the space requirements of other users of the sea.

1.3  Balance of Plant optimisation

This concerns methods aimed at improving all parts of a wind farm, with the exception of the turbines themselves. You can think of the foundations and the network connection as well as the components, from manufacturing to transport & installation and decommissioning.

1.4 Next Gen WTG  

This concerns the technology that is needed for the next generation wind turbines (of 25MW). Larger rotors for lower LCOE (levelised cost of energy) and more energy at low wind speeds contribute to costs reductions, increasing revenues and balancing of the grid. This is a longer term research objective and requires knowledge development in the field of:

  • aerodynamics,
  • large rotors at great heights,
  • application of new (structural) materials,
  • innovation of wind turbine components (generator, transmission),
  • new technologies such as multi-rotor, VAWT and airborne.

1.5 Floating Solar

This concerns research into the feasibility of floating solar energy in the Dutch North Sea. Theoretically, the potential is great. By means of research and experiments, it can be determined what is technically and economically necessary to actually apply and scale this up.

2. Integration into the Energy System

Illustration Integration into the Energy System

The integration into the energy system addresses the integration problem of very large quantities of renewable electricity from the sea. Possible solutions for this such as transport, storage, conversion, and chain coordination. However, there are costs associated with these flexible solutions that must also be reduced.

3. Integration into the environment (ecology and multi-use)

Illustration Offshore Wind and the Environment

This concerns the development of methods for building wind farms in such a way that the negative effects of this use of space on other users of the North Sea (such as fishing, nature and the environment, shipping, alternative forms of energy extraction and food production at sea) are mitigated as much as possible. The intention is to stimulate positive effects as much as possible in the pursuit of a net positive contribution.

Technology Readyness Levels (TRL’s)

The MMIP focuses on technical, social, spatial, ecological, economic and institutional change issues at all TRL levels. For the short term (results within 5 years) the emphasis is mainly on making smart incremental innovations available for acceleration, acceptance and safety. For the medium term (results available in the period up to 2030), structural innovations are needed for further cost reduction and the usability in the energy system and environment, such as increasing the capacity factors of offshore wind farms, new foundation technology, digitization and robotization of installation and maintenance. For the longer term (technology available after 2030), possible breakthrough technology is being investigated such as off-grid wind farms, airborne wind, offshore solar energy and ocean energy.
